The ATK mill is mated to a 727 transmission and a NV249 AWD transfer case. The engine is operated using an AEM engine management system that was installed by Pat Smith, who also completed the remaining vehicle wiring and plumbing. Pat and Skyler Gambrell are the main mechanics on the race Jeep. After all was installed, AEM engine tuner Mitch Peterson made a house call to Jon's place and dialed in the AEM system.
